Abstract the paper proposes special multiple input single output synthetic aperture radar (miso sar) and multiple input multiple output sar (mimo sar) for bidirectional imaging, which can simultaneously illuminate two areas from different directions in azimuth.
Aasr Of The Proposed Mimo Sar Versus Acquisition Prf Download This paper presents the system design of these modes and analyzes their azimuth ambiguity to signal ratio (aasr). Similar to the single channel bidirectional sar system, the cyclic behavior of divergent and coincident folding also becomes visible by plotting the aasr versus the selected prf as shown in figure 4. Therefore, this imaging scheme is named miso sar.tosuppresstheinterferencebetweenechoes,twotrans mittedsubpulsescouldbewithdifferentcarrierfrequencies, and their corresponding echoes are. As shown in fig. 5, the proposed aasr estimation technique can be also used to show how the aasr of a staggered sar system varies for different interpolation methods, mean prfs, processed doppler bandwidths and mean duty cycles.
Simulation Results Of The Proposed Miso Sar With The Prf Of 5170 Hz Therefore, this imaging scheme is named miso sar.tosuppresstheinterferencebetweenechoes,twotrans mittedsubpulsescouldbewithdifferentcarrierfrequencies, and their corresponding echoes are. As shown in fig. 5, the proposed aasr estimation technique can be also used to show how the aasr of a staggered sar system varies for different interpolation methods, mean prfs, processed doppler bandwidths and mean duty cycles. It is worth remarking that this paper is not focused on the design of orthogonal waveforms, and we aim to give a precise evaluation of the azimuth ambiguity to signal ratio (aasr) and range ambiguity to signal ratio (rasr), which is very important for the design of spaceborne sar systems. In response to the problem, an optimal design using the golden section method has been proposed in this paper. after establishing a squint sar imaging model, the azimuth spectrum of the entire scene is analyzed, and the azimuth bandwidth is obtained by the golden section method. The space sampling characteristic is sensitive to changes in pulse repetition frequency (prf). this paper presents a method for optimizing the prf of a distributed mimo sar system based on the performance of the latter. the optimized prf adapts well to variations in satellite spacing. The current paper describes the spectrum separation effects, aasr analysis, and the system design process. therefore, to confirm effectiveness, point target 1 d and 2 d simulation results are compared before and after the improvement.
